PS Vita 3.72 Downgrade to 3.65 Now I have a brick, help?


when i try to turn on the screen stays black
and when i go through safe mode i can only update the system software

so i tried to update it via pc by downloading firmware 3.73 and qcma but it works and stops at 7% with an error message. then 2 months later I try to resume everything but this time it does not even advance it remains at 0% I waited for hours but nothing.
really I'm lost that someone can help me find a solution

Try putting 3.72 back on would be the best idea if the newest firmware is not working.
